RE: [Zope] The logic of the _ variable (Q1959)

<dtml-var expr="_.render(_['x'])"> looks in the current Document Template namespace for a variable named 'x' and renders it fully.

It works but I have never see mention of this _ method in the documentation. Is it new? Is it possible to display a list of all the attributs of the _ variable. (Something like _.keys())

to get at with <dtml-var expr="x(_,_.None)">.

I have never seen that too. Is it somewhere in the docs? I tried : <dtml-var "index_html(_,_.None)"> I got: Error Type: KeyError Error Value: standard_html_header I find it really interesting to understand the magic of these expressions. Thanks for your comments. *************************** Oscar Picasso picasso@videotron.ca ***************************
